Abstract :
Wireless laser communication can be employed in ldquothe last one kilometerrdquo access problem. There are two methods of modulation, digital modulation and analogue modulation. Digital modulation is easy to adopt modern channel coding technique and it has very strong ability of anti-jamming. We introduced a wireless laser data transmission system which is adopted in video data transmission. In this system, we adopt pulse position modulation to enhance the ability of anti-jamming, and choose RS (15, 9) to conquer three bits errors and employed DSP and FPGA to implement.
